# 一带一路

[Live example](https://l7.antv.antgroup.com/en/examples/gallery/story/yidaiyilu/)

[Resource index](/llms.txt)

Provide a DOM element with `id="container"`. The original example source follows.

## Source

```js
import { LineLayer, PointLayer, PolygonLayer, Scene } from '@antv/l7';
import { GaodeMap } from '@antv/l7-maps';

const scene = new Scene({
  id: 'map',
  map: new GaodeMap({
    style: 'light',
    center: [60.268, 30.3628],
    zoom: 1.5,
  }),
});
scene.on('loaded', async () => {
  scene.addImage('local', 'https://gw.alipayobjects.com/zos/rmsportal/xZXhTxbglnuTmZEwqQrE.png');
  const belt = await (
    await fetch('https://gw.alipayobjects.com/os/rmsportal/UpapMomPYUeiBjbHNAma.json')
  ).json();
  const line = await (
    await fetch('https://gw.alipayobjects.com/os/rmsportal/kwUdcXnxQtexeGRvTGtA.json')
  ).json();
  const line2 = await (
    await fetch('https://gw.alipayobjects.com/os/rmsportal/dzpMOiLYBKxpdmsgBLoE.json')
  ).json();
  const point = await (
    await fetch('https://gw.alipayobjects.com/os/rmsportal/opYqFyDGyGUAUXkLUhBV.json')
  ).json();
  const fillLayer = new PolygonLayer({
    autoFit: false,
  })
    .source(belt)
    .color('cname', function (value) {
      return value == '中国' ? 'rgba(46,149,169,0.45)' : 'rgba(227,244,244,1)';
    })
    .shape('fill');

  const linelayer = new LineLayer().source(line).color('rgb(79,147,234)').size(1.5).shape('line');

  const linelayer2 = new LineLayer()
    .source(line2)
    .color('rgb(11,94,69)')
    .size(1.5)
    .shape('line')
    .style({
      // 'lineType':'solid'
    });

  const pointlayer = new PointLayer({}).source(point).size(12.0).shape('local');

  const textlayer = new PointLayer({})
    .source(point)
    .size(12.0)
    .shape('name', 'text')
    .color('#027aff')
    .style({
      textOffset: [0, -42],
      stroke: '#fff',
      strokeWidth: 2,
      textAnchor: 'bottom',
    });
  scene.addLayer(fillLayer);
  scene.addLayer(linelayer);
  scene.addLayer(linelayer2);
  scene.addLayer(pointlayer);
  scene.addLayer(textlayer);
});
```

## Runtime environment

Before evaluating the example, await this setup in a page containing #container. Supporting files follow below.

```js
await (await import("/src/demo/setup.ts")).default({ container: document.getElementById('container'), path: "/examples/gallery/story/demo/yidaiyilu.js" });
```


## src/demo/setup.ts

```ts
import type { DemoSetupContext } from '@antv/astro-theme-antv';
import * as District from 'district-data';
import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader.js';

export default async function setup({ container, path }: DemoSetupContext) {
  // Tool pages provide their own React layout and SDK imports.
  if (!path.startsWith('/examples/')) return;
  // Retain only the original globals still used by gallery examples.
  Object.assign(window, { District, GLTFLoader });
  const map = document.createElement('div');
  map.id = 'map';
  container.append(map);
  await import('./map.css');
  // Match the original gallery's shared AMap environment, including raw AMap demos.
  await import('./amap');
}
```

## src/demo/map.css

```css
#map {
  position: relative;
  width: 100%;
  height: 100%;
  min-height: 320px;
}

.labelclass {
  position: absolute;
  display: inline;
  cursor: pointer;
  background: rgb(255, 228, 120);
  border: solid 2px #fff;
  padding: 4px;
  white-space: nowrap;
  font:
    bold 12px/18px arial,
    sans-serif;
  color: #fff;
  border-radius: 50%;
  width: 40px;
  height: 40px;
  line-height: 30px;
  /* opacity: 0.7; */
  text-align: center;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}
```

## src/demo/amap.ts

```ts
import AMapLoader from '@amap/amap-jsapi-loader';

// Preserve the site's development and production SDK registrations.
const credentials = import.meta.env.DEV
  ? { key: '6f025e700cbacbb0bb866712d20bb35c', securityJsCode: '290ddc4b0d33be7bc9b354bc6a4ca614' }
  : { key: 'f59bcf249433f8b05caaee19f349b3d7', securityJsCode: '2653011adeb04230b3a26cc9a780a800' };
window._AMapSecurityConfig = { securityJsCode: credentials.securityJsCode };
await AMapLoader.load({ key: credentials.key, version: '2.0', plugins: ['Map3D'] });
```
